In case you need to whitelist the AddSearch Bot in your site’s configuration, the best option is to allow it by it’s User-Agent. It is in the form of:
Mozilla/5.0 (compatible; AddSearchBot/1.0; +http://www.addsearch.com/bot/)
The version might differ, but the User-Agent will always contain the identifier “AddSearchBot”.
In case letting our user-agent through is not possible, below is a current list of our bots’ IP addresses. Please note that the servers taking screen captures are currently using a pool of dynamic IP addresses that we have no control over, so the screen captures in your search results might not work.
